Significant cross talk occurs between inflammation and coagulation. Thus, coagulopathy is common in sepsis, potentially aggravating the prognosis. Initially, septic patients tend to exhibit a prothrombotic state through extrinsic pathway activation, cytokine-induced coagulation amplification, anticoagulant pathways suppression, and fibrinolysis impairment.

Several causes contribute to the high infection rate in tumor prostheses, including extensive tissue dissection and patients' immunosuppression due to the neoplastic disease. Most of these infections develop within the first 2 years following surgery with 70% of them occurring during the first year, while they are often associated with a low pathogen burden. The pathogenesis of infections in tumor prostheses is linked to bacteria developing in biofilms.

Monkeypox has emerged as a significant human pathogen, posing severe risks in vulnerable populations. At present, there is not enough data available as to whether pregnant women are more vulnerable to monkeypox infection, or they suffer more severe symptoms, and studies on this issue as well as to the possible adverse effects on the developing fetus are limited. The aim of this review, was to bring together what is known so far about monkeypox virus transmission, the clinical course of the disease, and associated maternal-fetal outcomes.

Panagglutination on the indirect antiglobulin test is one of the most challenging dilemmas of pretransfusion testing. It occurs when patient sera react with all red blood cells tested, that is, with both screening and identification panel cells. Two main questions must be answered.

Studies on the humoral response to homologous BNT162b2 mRNA-vaccination focus mainly on IgG antibody dynamics, while long-term IgA kinetics are understudied. Herein, kinetics of IgG and IgA levels against trimeric-Spike (S) and Receptor-Binding-Domain (RBD) were evaluated by in-house ELISAs in 146 two-dose vaccinated Greek healthcare workers (HCWs) in a 9-month period at six time points (up to 270 days after the first dose). The effect of a homologous booster third dose was also studied and evaluated.

Extraintestinal manifestations of celiac disease (CD) are an integral part of the disease's clinical profile and, frequently, appear as the presenting feature. Given that anemia in CD may be multifactorial, increased awareness is needed on the part of treating physicians, and especially hematologists, to screen for CD. In this study, we highlight anemia as the presenting feature of CD which has remained undiagnosed for several years.

The early period of infection with human immunodeficiency virus (HIV) has been associated with higher infectiousness and, consequently, with more transmission events. Over the last 30 years, assays have been developed that can detect viral and immune biomarkers during the first months of HIV infection. Some of them depend on the functional properties of antibodies including their changing titers or the increasing strength of binding with antigens over time.

Bone and joint infections are associated with a devastating global burden. The successful treatment of these infections requires a multidisciplinary approach between orthopedic surgeons and experts of different disciplines. This multidisciplinary approach has gained ground over the past decades in modern infection units as a more effective treatment strategy, yielding better outcomes regarding infection eradication rates, length of hospital stay, and overall cost of treatments.

Objectives: The International Haemovigilance Network's (IHN) ISTARE database collects surveillance data on all adverse reactions (AR) associated with transfusion of blood and blood components, facilitating the sharing of best practice and benchmarking for improving blood safety and quality. Up to 2012, no publications discussed certain rare AR. The aim of this study is to examine ISTARE data on AR from 2012 to 2016, focusing on hypotensive reactions, post-transfusion purpura (PTP), transfusion-associated graft versus host disease (TA-GvHD), hyperkalemia and hypocalcemia.

In-depth understanding of the immune response provoked by SARS-CoV-2 infection is necessary, as there is a great risk of reinfection and a difficulty in achieving herd immunity due to a decline in both antibody concentration and avidity. Avidity testing, however, could overcome variability in the immune response associated with sex or clinical symptoms, and thus differentiate between recent and past infections. In this context, here, we analyzed SARS-CoV-2 antibody kinetics and avidity in Greek hospitalized (26%) and non-hospitalized (74%) COVID-19 patients (N = 71) in the course of up to 15 months after their infection to improve the accuracy of the serological diagnosis in dating the onset of the infection.

Management of Coagulopathy in Bleeding Patients.

J Clin Med

December 2021

Transfusion Service and Clinical Hemostasis, Saint Savvas Oncology Hospital, 115 22 Athens, Greece.

Early recognition of coagulopathy is necessary for its prompt correction and successful management. Novel approaches, such as point-of-care testing (POC) and administration of coagulation factor concentrates (CFCs), aim to tailor the haemostatic therapy to each patient and thus reduce the risks of over- or under-transfusion. CFCs are an effective alternative to ratio-based transfusion therapies for the correction of different types of coagulopathies.

December 2021

First Department of Pathology, Medical School, National and Kapodistrian University of Athens, Laiko General Hospital, Mikras Asias 75, 11527 Athens, Greece.

This is the first study aiming to investigate mTOR signaling and its relation to mismatch repair status (MMR status) in colorectal cancer (CRC). MMR status and the phosphorylated proteins, pmTOR and p4EBP1, have been immunohistochemically analyzed in 108 formalin-fixed, paraffin-embedded CRC specimens. The correlations between them and with clinicopathological data, MAPK pathway (KRAS, NRAS, BRAF) as well as their impact on patients' overall survival have been statistically analyzed.

COVID-19 is an ongoing pandemic with high morbidity and mortality. Despite meticulous research, only dexamethasone has shown consistent mortality reduction. Convalescent plasma (CP) infusion might also develop into a safe and effective treatment modality on the basis of recent studies and meta-analyses; however, little is known regarding the kinetics of antibodies in CP recipients.

Article Synopsis
  • A multicenter phase II study investigated the efficacy and safety of convalescent plasma (CP) infusion for patients with severe COVID-19 (grade 4 or higher).
  • Results showed that 93.3% of CP recipients fully recovered within 28.5 days, with a lower death rate of 3.4% compared to 13.6% in the control group.
  • Higher antibody levels in the CP were linked to a significantly reduced risk of death, indicating that early CP infusion may be a safe and effective treatment for severe COVID-19 cases.

We evaluated the antibody responses in 259 potential convalescent plasma donors for Covid-19 patients. Different assays were used: a commercial ELISA detecting antibodies against the recombinant spike protein (S1); a multiplex assay detecting total and specific antibody isotypes against three SARS-CoV-2 antigens (S1, basic nucleocapsid (N) protein and receptor-binding domain (RBD)); and an in-house ELISA detecting antibodies to complete spike, RBD and N in 60 of these donors. Neutralizing antibodies (NAb) were also evaluated in these 60 donors.
